How Frequently Should I Get A Whole House Rewire?

Given our work in the electrical industry, we get hit with this question pretty often, especially if we’re out on a routine inspection and doing a quote for an entire house rewire. Clients worry that they might have left their current wiring in too long. They also fret over how long a fresh house rewire is going to last for them.

Just How Long Will A Whole House Rewire Last?

A good house rewires ideally lasts for two decades, if not more. Some even last 40 years, although in time the cable insulation starts breaking down, meaning a house rewire is inevitable. An electrician can check your wiring out for you.

Having said all that, there aren’t actually guidelines set for just how long a good rewire lasts. What really determines it is just how your property gets used and what specific materials are utilized for the wiring. Much older rewires put materials into the place that aren’t considered suitable by modern standards, especially if they have tough rubber sheathing or lead cabling. This is why much of the advice you find will recommend a rewire if you have electrics more than 20 years in age. That alone can bring your property up to current rules and regulations.

If you want to be sure that the wiring you have is safe, then you need to have routine inspections conducted by an electrician who is totally registered and qualified. It should happen every 10 years in a property that you live in. Rental properties should have this done every 5 years. This will keep electrics current and safe.

You can also do regular checks as a homeowner yourself, and you, in fact, should do so. Here are a few things that you should watch for:

  • Cable condition
  • Condition of switches and sockets
  • Any buzzing noises
  • Blown fuses
  • Discolored sockets

Should you discover any such issues, then you need to have a registered electrician check them out promptly.

What Steps Can You Take To Extend The Life Of Cabling?

Sheathing and insulation around cables are likely to deteriorate with age, although one frequent issue our electricians commonly encounter during installations and inspections is the cabling that hits high temperatures from overloading, cables sitting in direct sunlight, and cables being close to excessive heat sources.

Deteriorated cables aren’t safe to use since they start losing their insulation. They also get less flexible, which results in their breakage or the sheathing starting to crumble away. This might pose a fire risk or electric shock.

The most frequent reason for overloading cables is due to excessive appliances all on one single circuit and being used simultaneously. An overloaded plug socket might happen because of kettles, irons, and microwaves, or hairdryers and hair straighteners.

Never overload a plug socket if you want to maintain your home’s cabling conditions. Arrange for one of our many qualified electricians to install extra sockets. Make sure that your laundry machines each run off a socket of their own rather than extension leads. Be sure that your cabling isn’t exposed to direct sunlight or high temperatures.

Maintain the safety of your family and home by checking up on your electrics regularly. If you find anything circumspect, contact us or call us for a trusted electrician.
